Leaf, Key, and Type-moon has been three of the most popular eroge topics at Comiket since the late 90s and more than a handful of people have probably been wondering about the exact number of circles that actually did doujin stuff from these three.
The National Diet Library in Tokyo has every single edition of the Comiket catalog in its archives and August Dojin Data Base took the opportunity to compile a pretty good list of the number of circles that have been doing Leaf, Key or Type-moon doujins during each Comiket starting from Comiket 56 held in 1999 August.

The big drop in circles during Comiket 67 and 69 was due to the fact that they were held for only two days during the winter Comiket instead of three days like during Comiket 63, 65, 71, and 73. Also Comiket 61, 59, and 57 were 2 days, while all the summer Comikets are 3 days.
The highest total combined number of circles with was 1,578 circles during Comiket 63, and in the last two Comikets the total has been approximately 1,100 circles. Given that Comiket is held for only 6 hours, it means that you’d have to go at a rate of 4.6 circles per minute if you wanted to go through every one of these circles.
Leaf
The highest that Leaf ever reached was 810 circles during Comiket 58, thanks to the combined powers of the totally awesome To Heart TV series, the release of the PSX version of To heart, and the release of Comic Party. The amount of circles doing Leaf stuff had been going down but went up again during the periods following the release of Utawarerumono, Utawarerumono TV series, and ToHeart2.
Key
The majority of the circles doing Key stuff chose to do something based on Kanon. Air as a game had sold more than Kanon when it was released, but in the doujin scene Kanon has always been more popular. The total number of circles that did Kanon stuff over the years was 3,284 circles, while the total number of circles that did Air stuff was 1,167 circles. The number of circles doing Key stuff had been decreasing too, but went up again in December due to the release of Little Busters.
Type-moon
Tsukihime took about a year and a half after its first release before it got its major break in the doujin scene. The highest that Type-moon ever went was 692 circles in Comiket 66, which isn’t as high as Leaf as its peak, but the total number of circles doing Fate/Stay Night was 613 circles during Comiket 70, which is the highest number of circles doing on one game amongst all the games from the other brands.
Etc
As compared to the amount of time taken for Tsukihime to break into the doujin scene, Higurashi took about 3 years before it got its major break in doujin. So if Himawari was to ever have its major break, it probably won’t be soon yet.
Also, I briefly checked the number of Touhou related circles in the last Comiket and there were over 600 circles. It sure explains all those overcrowding problems during the recent Reitaisai.
